In a very short time, Rand Paul has become a major force in politics. He appeals to the far right and left, with his odd blend of isolationism and libertarianism, and very well could be the next US President. Also, many leftists like Rand Paul for the same reason they like his dad: his hostility to Israel. Rand Paul, if elected President, will follow the same toxic land for piss policies of the left.
I don't trust Rand Paul, and I despise his father, so I will support another repub candidate. Perhaps Ted Cruz will emerge; he seems pretty good, is right on most issues, and has enough charisma to blunt Rand Paul's appeal to right wingers.
